Baires:
Who benefits? The corporate elite which includes the banks. The American, Mexican and Canadian people are merely fodder to be used for exploitation.
The North American Union was a condition for entering into NAFTA and is to be accomplished before 2010. This means there are only 21 months left to accomplish this goal. Many aspects of this union have already been carried out at the bureaucratic level behind closed doors. The average guy in the street does not have a clue that his own country is being dismantled in front of his eyes. If he knew he would be outraged. This is why all the proceedings take place in secrecy and the information that is released into the public domain is brilliantly manipulated to deceive the public (e.g. Security & Prosperity Partnership Agreement).
What is important to realize is that the North American Union and many other developments in other areas are merely precursors to a World Government. A World Government contemplated here is one where the corporate elite are the masters and everybody else becomes a slave. The concept of a World Government here is a feudal system.
